| (54) | Inter-process signal handling in a multi-processor system |
| (57) There is disclosed a multi-processing arrangement in which processes running on one
processor may utilize processes, called stub processes, running on other processors.
One problem that occurs with respect to such a system is that signals, which indicate
the occurrence of external asynchronous events, must be processed in a specified order
if the system is to work properly. Disclosed is a system for insuring the proper processing
of such signals by requiring all such signals to be routed from a receiving process
on a adjunct processor to the main user process on the originating processor. Also
disclosed is an arrangement for insuring that signals are not lost and that duplicate
signals are not processed. |
